Acacia Swimwear: Bali-Crafted, Hawaii-Inspired

You know an Acacia the moment you see it. There is no mistaking the cut: a high-arc hip, a cheeky-but-never-gratuitous seat, string ties that land exactly where they should, and a fit so precise it seems engineered rather than sewn. The prints feel painted rather than printed — tropical florals in muted ochre and orchid, geometric chevrons, snakeskins rendered in ink that reads like watercolor, the kind of colorways that come from somewhere specific rather than a trend board. That specificity is not accidental. It is the product of a designer who grew up on the North Shore of Maui, spent formative years in Bali's ateliers, and then built a brand around the intersection of those two worlds — one defined by the spirit of aloha, the other by generations of artisan craft. Acacia is not a swimwear brand with a story bolted on. The story is the swimwear.
The Founding: Two Islands, One Vision
Naomi Acacia Newirth was sewing her own bikinis in high school on Maui long before she had a brand name or a business plan. Growing up surfing the breaks at Ho'okipa on Maui's North Shore — a beach so synonymous with wave riding that it would eventually lend its name to one of the brand's most enduring silhouettes — she knew exactly what she wanted from a swimsuit: minimal hardware, a precise fit, a bottom that actually stayed put in the water, and a cut that honored the way island women actually wore their suits. What she found in stores repeatedly failed on every count.
After completing her degree at the Fashion Institute of Design & Merchandising in Los Angeles, Newirth made extended trips to Bali, where she designed for an apparel company and deepened her understanding of swimwear construction. Those years in Indonesia were formative — not just technically, but philosophically. She saw what was possible when craft, time, and the right materials converged. She began to see exactly how Acacia could be made. She returned to Hawaii and, in 2010, launched the brand officially with her friend Lyndie Irons — a Southern California-raised swimsuit model and wife of the late world champion surfer Andy Irons from Kauai — who brought her own lifelong passion for swimwear design to the partnership. The brand's name comes from Newirth's middle name, meaning stability and purity: fitting cornerstones for a label built on structural precision and uncompromising materials.
The early years were not easy. Newirth was living in California, doing sales calls and trunk shows, hearing repeatedly from buyers that her cuts were too daring, too small, too far outside the mainstream. She pressed on. "We grew slow," she has said, "but I got to learn the business from the inside out." When she eventually moved back to Maui, the brand found its footing. Returning to the island that had shaped her aesthetic turned out to be the catalyst: rooted again in the landscapes, the light, and the community of her home, Acacia became the label it was always meant to be.
The Bali Connection: Craft Over Volume
Every Acacia swimsuit is made in Bali, Indonesia — and has been, in the same factory, for well over a decade. This is not outsourcing for the sake of cost. It is a deliberate relationship with an artisan production system that Newirth understands intimately from her own time designing there. The factory has scaled with Acacia over the years, maintaining the kind of close collaboration that allows for the intricate details the brand is known for: precise seamless construction, the soft-hand crochet work that avoids the fit failures common in mass-produced versions, and the meticulous application of custom prints that require care at every stage.
As reported by Sports Illustrated Swimsuit, Acacia is ethically manufactured in the same factory in Bali it has worked with for over twelve years, with every swimsuit produced on a made-to-order basis and packaged in fully compostable materials. Newirth runs the brand consciously — employing a collective of Hawaii-based women as designers, donating a percentage of every purchase to an environmental or social justice non-profit, and continuously reevaluating materials. In its eleventh year of operation, Acacia committed publicly to transitioning to clean production practices, introducing REPREVE recycled swim fabric (regenerated from recycled plastic bottles into the softest nylon), TENCEL (derived from sustainably harvested trees), OEKO-TEX certified organic linen, and Cotton Crupo (regenerated cellulose fibers from recycled cotton linter). All packaging is compostable. The made-to-order model minimizes overproduction waste. These are not marketing footnotes — they reflect the same exacting standard applied to the fit.
Newirth has described the original production process with characteristic directness: she hand-sewed the first collections herself in a studio in Makawao on Maui's upcountry, letting girlfriends swing by to pick out suits before the pieces were sent to Bali to be replicated and scaled. That loop — design in Hawaii, craft in Bali — remains the structural logic of Acacia to this day.
The Fabric: Italy Meets the Pacific
From the brand's earliest collections, Acacia has sourced its base fabrics from Italy. The original formula — 80% nylon, 20% spandex — established a standard for stretch, opacity, and color retention that cheap polyester blends cannot touch. Italian swimwear fabrics are designed to hold their pigment through saltwater, chlorine, and sun exposure in ways that genuinely affect how a suit looks a season from now versus the day it arrived. Acacia's transition to recycled nylon in recent years has maintained that Italian-quality standard while shifting the sourcing toward recycled feedstocks — the regenerated nylon carries the same buttery hand-feel that Acacia customers have come to associate with the brand.
The current fabric breakdown across the range reflects the brand's evolving material vocabulary: core swim styles use 80% Recycled Nylon / 20% Spandex; ribbed textures run 85–92% Recycled Nylon or Polyester / 8–15% Spandex; lining is 85% Nylon / 15% Spandex. The crochet styles use a soft silk blend (historically) or recycled nylon in the current Recycled Crochet editions, avoiding the rough, ill-fitting hand of standard crochet knits. All of this adds up to a suit that moves with the body, holds its shape, and feels like nothing else at the price point.
The Print Language: Nature Rendered by Hand
Acacia's prints are not licensed patterns purchased from a print house. Naomi Newirth designs every print herself — and she designs the lining prints as well, the interior layer of color and pattern that most brands treat as an afterthought. "It's just the little details that make it fun," she has said. The result is a visual consistency that runs from the outermost layer of a suit to its lining: color stories that work across both sides of the fabric, unified by the same hand and the same sensibility.
The print vocabulary draws from specific geographies. The 2016 Hawai'i Nei collection — whose name translates literally to "Beloved Hawai'i" — was inspired directly by the landscapes of Maui: Hana's red sand beach at Kaihalulu, the waterfall at Pua'a ka'a, the black sand of Wai'napanapa, the turquoise pools of Waioka. These are not generic tropical references. They are the actual places where Newirth grew up. Later seasonal print work extended into geometric patterns, subtle snake prints, painterly florals, and chevrons — always with that same signature quality of feeling observed rather than invented. The Resort 2025 collection showcased prints drawn from the unconventional beauty of nature and geometry, rendered with the paint-like, no-bleed quality of pigment inks that pop on both light and dark surfaces. The Vintage Aloha capsule extends the brand's most iconic Hawaiian-inflected print language across its core silhouettes, creating small-batch colorways that cycle in and out of production seasonally.
The colorways themselves follow a similar logic: not trend-driven neons or safe neutrals, but specific, considered selections — muted sage, ochre, deep rust, orchid-purple, tropical magenta, soft natural tones alongside vibrant pops. They read as a palette assembled by someone who has spent time watching specific light fall on specific water.
Hero Silhouettes: The Styles That Define the Brand
Acacia has built its reputation on a handful of silhouettes that recur season after season, refined but recognizable across years of production.
Ho'okipa Bottom — Named for the legendary North Shore surf break where Newirth grew up, the Ho'okipa is the brand's best-selling signature bottom. It delivers minimal coverage with a high-arc hip cut, sitting at the sweet spot between cheeky and elegant. The cut is the reason the brand exists: Newirth founded Acacia because nothing in the market offered this exact profile — sophisticated enough to wear off the beach, daring enough to actually honor the body. The Ho'okipa currently retails at $124 in core seasonal colorways and $128 in the Vintage Aloha capsule.
Ralphy Bottom — A companion signature, the Ralphy offers minimal coverage with a high-cut hip and adjustable side straps for a fully personalized fit. The adjustable ties adapt the silhouette as you move, giving it an ease that fixed-waist bottoms cannot match. The Ralphy retails at $124 in seasonal colors across the Summer and Resort collections.
Kokomo Full Piece — The brand's best-selling one-piece, the Kokomo features architectural cut-out strap details in both the front and back, fixed shoulder straps, and a standard straight-across rise on the hips. The cut-outs are precise and structural — not the decorative lattice of fast-fashion one-pieces, but specific negative space that shapes the silhouette. It retails at $234, constructed from 80% Recycled Nylon / 20% Spandex.
Baja Crochet Top — The Baja is a triangle-style crochet top with adjustable straps, executed in Acacia's signature soft-hand crochet that avoids the fit problems common to knitted swim. Conventional crochet tops gap, stretch unevenly, and lack the structural support of a woven suit. Acacia's Baja avoids all of this. The Resort 2025 version retails at $154 in the Recycled Crochet construction.
Lisboa Crochet Top — Another crochet entry from the Pre-Fall 2025 collection, the Lisboa brings the brand's craftsmanship language into a cooler, more architectural shape at $150.
Humuhumu Crochet Top — Named for the humuhumunukunukuapua'a, Hawaii's state fish, the Humuhumu brings textural depth to the crochet category with Hawaiian-inflected naming that runs through the brand's vocabulary.
Across the bottoms range: the Queens ($132), Oslo ($124), Zuma ($124–$159 depending on fabric), Seychelles ($132), Relle Piped ($150), and Tommy Piped ($157) each occupy distinct positions within Acacia's coverage-and-cut spectrum, from mid-coverage cheeky to minimal. One-pieces — including the Stella, Pepper, Sloane Piped, Tess, Marlow, and Bronx — range from $234 to $264. Tops span $115 to $165 across the current seasonal range.
Sports Illustrated Swimsuit and the Editorial Landscape
Acacia's national debut came early and emphatically: a bikini from the brand's first collection appeared in the 2011 Sports Illustrated Swimsuit Issue, the year after launch. This was the opening act of a long relationship with the world's most-watched annual swim editorial. By 2015, the brand had become a fixture of SI Swimsuit shoots — tennis champion Caroline Wozniacki wore Acacia for the 2015 issue, shot on Captiva Island, Florida, and model Hannah Ferguson appeared in Acacia in the same issue, photographed on Route 66. The brand's ability to hold its own across wildly different settings — a Florida island, a desert highway — speaks to the versatility of its silhouettes.
Sports Illustrated Swimsuit has since profiled Newirth directly as a founder, calling her "the cheeky bottom expert" and crediting her as the designer who was first in the industry to offer "a cheeky, but not thong-like bottom" — a distinction that is now widely copied across the swim market. The brand is described on SI Swimsuit's own platform as a "celebrity and SI Swimsuit favorite."
Celebrity placement has followed naturally from that editorial credibility. Beyoncé was photographed on a yacht wearing Acacia's Florence snake-print one-piece — a $205 side-cut-out swimsuit with architectural strap detailing — in a widely circulated 2015 image. Rihanna has also been documented in the brand. Harper's Bazaar, Elle, and InStyle have all featured Acacia's seasonal releases. The brand debuted at Mercedes-Benz Fashion Week Swim in Miami in 2011, its first year of national distribution, and has since shown at Funkshion Fashion Week Miami Beach and Paraiso Miami Swim Week across multiple seasons — including a headline-generating Resort '25 show at the iconic 1111 Lincoln Road during Paraiso in June 2024, where Acacia partnered with Sharpie Creative Markers to demonstrate its print-development process live on the runway.
That runway moment was characteristic of the brand's approach to its own story: rather than staging a conventional show, Acacia used the platform to make its print philosophy visible — demonstrating how the hand-applied, paint-like quality of its ink work translates from sketch to swimsuit.
The Aesthetic DNA: What Makes Acacia Instantly Recognizable
Acacia occupies a specific position in the luxury swim market that very few brands have managed to hold consistently. It is not surf-brand casual — the cuts are too deliberate, the fabrics too refined, the prints too considered. It is not high-fashion swim divorced from actual water use — the construction is built for movement, the silhouettes are designed by a surfer for surfers. It sits at the intersection: genuinely wearable for an active ocean lifestyle, genuinely beautiful as fashion, and genuinely specific in its point of view.
The defining characteristics, season after season: seamless construction (no pinching, no unflattering seam lines, no hardware digging into hips or ribs); proprietary prints designed in-house by Newirth, including coordinating lining prints; a signature bottom cut that sits high on the hip arc without becoming a thong; buttery Italian-sourced (and now recycled) nylon that holds its shape and color; crochet work executed in soft-hand materials rather than rough knit; and a color sensibility that reads as place-specific rather than trend-reactive. Maui Magazine has described Newirth's designs as "synonymous with the sexy, cheeky cuts that have redefined the industry." That redefinition is real — the cheeky bikini bottom that is now ubiquitous across the premium swim market owes a significant debt to what Acacia introduced in 2010.
In 2019, Acacia opened its first flagship boutique at 24 Baldwin Avenue in Paia, on Maui's North Shore — the same town where it all started, close to the beaches that gave the brand its visual language. The store carries the full collection alongside curated denim (Ksubi, Re/Done) and accessories selected by Newirth herself. The brick-and-mortar is less retail strategy than homecoming.
How to Style Acacia
The Signature Set — Pair the Ho'okipa or Ralphy Bottom with one of Acacia's structured tops — the Baja Piped, the Wren, or the Ruby Piped — in a matching colorway from the same seasonal drop. The piped styles add a graphic edge to the clean silhouette; wear with a Re/Done denim cut-off or a linen shirt left open. This is the Acacia look in its most complete form.
The Crochet Moment — The Baja or Lisboa Crochet Top pairs naturally with minimal solid bottoms in a coordinating tone. Crochet tops carry texture on their own; the bottom should stay quiet. Wear the set with flat leather sandals and a raffia bag — Acacia's RTW pieces (the brand now offers elevated ready-to-wear alongside swim) work easily as beach-to-street coverup layers.
The One-Piece Edit — The Kokomo Full Piece or Pepper Full Piece works as a stand-alone outfit with high-waisted trousers or a maxi skirt. The cut-out strap details on the Kokomo read as a bodysuit; the Pepper's silhouette is clean enough to transition off the beach without a coverup. Add gold jewelry and slip-on shoes.
The Vintage Aloha Capsule — Acacia's small-batch capsule drops — like the Vintage Aloha series — present the brand's Hawaii-inspired print language across its core silhouettes in limited-run colorways. These are the pieces that sell through quickest and do not return. If you see a Vintage Aloha colorway in your size, treat it as what it is: a finite object.
Mix the Texture — Acacia produces several fabric textures within a single season — solid prints, triangle-textured fabrics, dual-ribbed constructions, smocked finishes — that are designed to work as mix-and-match within the seasonal palette. An Oslo Bottom in a textured fabric pairs with a solid-color Wren Top; a Zuma Smocked Bottom reads against a clean piped top. The prints and textures share the same underlying colorways, so mixing across finishes is intentional, not accidental.
